Internal structure models and dynamical parameters of the Galilean satellites (Q1890134)

NASA's Galileo mission to Jupiter has allowed major advantages in our understanding of Jupiter's moons Io, Europe, Ganymed, and Callisto over the past few years. Particularly, more precise geodetic data obtained during the Galileo mission make it possible to understand the internal structure of Galilean satellites. Here a short review of known models is presented, and another approaches to the modeling of Galilean satellites are proposed. Emden equations for the core and mantle is derived from the empirical bulk moduli without thermal corrections. Some recommendations for application of the models are given.
